Finder presents the new motion detector and occupancy type 18.5D with DALI (Digital Addressable Lighting Interface Interface). Specific for the reading of micro movements, it is suitable for applications in offices, schools, work environments in general.
The lens has been developed to obtain the best coverage of the micro movements, ensuring two reading areas of sensitivity and identified as “motion area” and “presence area”. The first – “motion area” – wide, covering an area of 8 x 8 meters; while the second – “presence area” – more important for the detection of small movements, covers an ‘area of 4 x 4 meters. According to the movement and the brightness read from the internal sensor, the 18.5D can be used in three different modes:
Comfort: regulates and maintains a constant brightness level according to the movement and daylight, increasing or decreasing the level of artificial light controlled. This feature allows significant energy savings and substantial comfort. Suitable for small offices, classrooms or workplaces.
Simplicity: it behaves like a simple motion detector, activates the lamps at 100% power. Report with power reduction to 50% for 20 seconds the impending shutdown. Avoid the sudden shutdown.
Friendliness: when the brightness level is lower than the set value, activates the artificial light to 10% of the power guaranteeing a minimum level of illumination. If motion is detected, the power of the lamps is adjusted to 100%, and maintained until the last detected movement. Report with power reduction to 50% for 20 seconds the impending shutdown. Suitable for common areas, lobbies, corridors, elevators zones.
With 18.5D type you can manage up to 8 DALI ballasts. Addressing is done in “Broadcast” ie all the DALI ballasts are “slave” and execute the command received by the motion detector. Some Product Specifications: Adjustable delay to shutdown from 10 seconds to 35 minutes; level of brightness adjustable from 10 lux to 800; power supply 110 … 230 VAC (50 / 60Hz). The new detector is supplied with all the accessories and supports suitable for mounting either recessed or ceiling.
